U N ll ll STEPHEN 0. DOUGHERTY, OF TORONTO, OHIU wesnine MACHINEApplication filed February 6, 1929. Serial No. 337,968.

This invention relates to laundry apparatus, and more particularly to amachine designed for domestic use for cleaning clothes, draperies, bedwear and analogous articles required to be washed.

The invention provides a machine which is portable and adapted to bedriven mechanically, and which admits of ready access to every part forcleaning, repairs, adjustment,

310 or other purpose, the operating parts being housed and protected.

While the drawingillustratesa preferred embodiment of the invention, itis to be understood thatin adapting the means to meet specific needs andrequirements, the design may be varied and such other changes in theminor'details of construction may be resorted to within the scope of theinvention as claimed, without departing from the spirit thereof.

F or a full understanding of the inventionand the merits thereof,reference is to be had I to the following description and the drawinghereto attached, in which Figure 1 is a perspective View of a washingmachine embodying the invention.

Figure 2 is an enlarged vertical, central sectional view. of thecomplete machine on the line 22 of Figure 3 looking in the directionindicated by the arrows.

Figure 3 is a horizontal sectional view on the line 3-3 of Figure 2looking downwardly as designated by the arrows.

Figure 4 is a detail perspective View of the agitator.

Corresponding and like parts are referred to in the followingdescription and ClGSignated in the several views" of the drawings bylike reference characters.

The machine is-mounted upon legs 1 which are supplied with suitablecasters to facilitate movement of the machine from one place to another.The numeral 2 designates the frame or body of the machine and consistsof a shell or casing. A compartment 3 is formed in the lower portion ofthe casing and receives the operating mechanism which is housed andprotected thereby. Access to the compartment 3 is had through an openingin a side of the casing which is normally ing oil to the lower hearing.The shaft 9 is open throughout and its top portion is square, or ofnon-circular formation to insure rotation of the agitator in a mannerexplained more fully hereinafter.

A top 10 is secured to the upper portion of the casing 2 and tub 6 andis depressed,

-the outer portion extending upwardly and retrorsely bent to embrace theedge portions of the tub and easing. A cover 11 closes an opening formedin the top 10. By having the top depressed drippings are caught anddirected back into the tub.

- The agitator comprises a base 12 of-circular outline and inclinedoutwardly and downwardly from a central point. Ribs 13 are provided uponthe upper side of the base 12 and have an approximate radialarrangement. A tube 14 projects upwardly from the base 12 andis of asize to slip over the upper portion of the tube 8 about which it is freeto rotate. ings 15 project outwardly from the tube 14 and providesupplemental agitating elements. A disk 16 is fast to the upper portionof the tube 14 and the upperen'ds of the wings 15 are connected theretoin any determinate way Other wings 17 above the disk 16 are attachedthereto and to the sides of the tube 14. The outer edges of the wings 17incline upwardly and inwardly, whereas the outer edges of the wings 15curve inward- 1y between their ends. A stud 18 depending from the upperclosed end of the tube 14 enters the upper end of the shaft 9 andprovides interengaging means to cause the agitator and shaft to rotatein unison. The base portion 12 of the agitator enters the top portion ofthe depression 7 and comes about flush with the bottom of the tub. Theagitator is readily removable and replaceable.

A wringer 19 of any approved construction is mounted at one side of themachine to swing laterally towards or away therefrom. The wringer shaft20 is mounted in a housing 21 at one side of the casing 2 and a train ofgearing connects itwith a motor 22 located within the compartment 3.

The train of gearing includesa shaft 23, to which power. may be appliedfrom any suitable source, as a motor 22. The motor 22 may be of any typeand connected directly to the shaft 23, or indirectly through a belt andpulleys in any determinate way. The shaft 23 is connected to a shaft 26by suitable gearing which as shown is of the worm type.

An arm 27 fast to the shaft 26 is connected tween the agitator and theshaft 9. It is to be understood that the usual clutch, not

shown, is provided between the wringer 1 mechanism and the shaft 20 andbetween the shaft 26 and the shaft 9 to admit of throwing i the wringerand the agitator into or out of action in the accustomed way as occasionmay requlre.

2. A washing machine agitator comprisribs disposed upon the top side ofthe lower disk and having an approximate radial arrangement, andoutwardly disposed wings connected. at their ends to the said disks, andat their inner edges to the tube.

3. A washing machine comprising a tub, a tube within the tub, a tubularshaft within the tube, an agitator including a tube closed" at its upperend and adapted to be slippedupon the first-named tube, and a studdepending from the closed end .of the agitator tube for detachableinterlocking engagement in the upper end of the shaft.

4. A washing machine comprising a supporting frame, a tub thereon, atube rising from the center of the tub and terminating adjacent the topthereof, a tubular shaft within the tube and stepped in the frame at itslower end, operating means on the frame connected with the lower endportion of the shaft below the tub, an agitator including a tuberotatably mounted upon the tube rising from the center of the tub andclosing the upper end thereof, and interengaging means between the upperends of the tubular shaft and the tube of the agitator to insurerotation of the latter.

In'testimony whereof I afiix my signature.

. STEPHEN O. DOUGHERTY.

The articles to be washed are introduced into the tub 6 and removedtherefrom through the opening closed by means of the cover 11. Theagitator may be placed within the tub or removed therefrom through theopening which is normally closed by means of the cover 11. The motor 22may be electric or of any type and when in operation imparts anoscillatory movement to the agitator through the connect-ionsillustrated in the accompanying drawings and described more.particularly herein.

The construction is such that it can be suc- 'cessfully used for washingfruit and vegetables, and when thus used the wringer mechanism maybeeliminated.

Having thus described the invention, I claim 1. A washing'machineincluding a casing having a bearing upon its bottom, a tub thereinhaving a depressed bottom, a tube projecting vertically from the centerof the depressed bottom and terminating adjacent the top ofthe tub, atubular shaft within the tube and having its lower end journaled in thebearing, an agitator mounted upon the. said tube and lnterengaging meansbetween the agitator and shaft.
